All the main tasks and multiplayer tasks have been collected, which can be better. My personal habit is to unlock, disguise, and hit health first, and then wait until Bilyk is finished before leaving the fighting department like Master of the Lance.
Skill points are used to upgrade your skills. Play more games, you can unlock more skills, or you can unlock the next skill. For example, if you upgrade the first-level unlocking, you can upgrade the second-level unlocking. Assassin points are used to upgrade your equipment, weapons can be used to enhance additional attack power, and clothing can be used to upgrade some attributes. Upgrade is role customization, and then click skills to upgrade the skills you want. Assassin points just click on the equipment bar, then click on weapons or clothing, and then upgrade the clothing or clothing you want.
